Comment (by varosi):

 I'm not that into GHC runtime and implications, but we could make some
 discussions on this topic and put it as opened issue for future work?

 Here is some talk:
 https://www.reddit.com/r/haskell/comments/6bpf3p/guard_pages_instead_of_heapstack_limit_checks_in/

 Sorry about the question, but why GHC's heap is linked list? Why not use
 linear virtual memory? Thread's stack could be linear, too. This will make
 much more easier and faster to access it.
